Spread some holiday cheer by not doing any of the things on this list while flying.

Polling at least a crowded plane toilet's worth of travel writers and other too-frequent fliers, we've conducted an unofficial survey of the most rude and irritating things you ... sorry, other people, do on planes.

Starting from the least frequently cited annoyance and ending with the humdinger of all irritants, here are the 20 most atrocious kinds of behavior we inflict upon each another at altitude.

The list could clearly be endless: let loose your own bugbears in the comments.

20. Abusing someone else's possessions in overhead bin

You arrived at the gate on time, boarded in orderly fashion and used your allotted overhead bin space for your nicely folded coat and new fedora.

Then Late Lummox arrives with a suitcase, stroller and shopping bag and mangles your dapper wear beyond recognition while shoving half his life possessions into a compartment meant for one personal item.

This one was actually raised by a leg-shaking travel author himself, who notes that, once, the woman next to him leaned over and placed a firm hand on his knee -- a unmistakable signal to still the hyperactive leg.

"I can only imagine the prolonged psychological drama that finally led to such an aggressive request," the tremulous author writes.

17. Boarding before group number is called

Most airlines have a system for getting hundreds of passengers aboard in the least amount of time.

That's why we schlep onto a plane as part of Group A or B or 1 or 4.

Granted, rubbing shoulders with the dirties in boarding group Y is like being stuck in the back row for a concert at Wembley.

And we're all familiar with the anxiety that comes with watching the multitudes board and snatching up all that overhead bin space.

And if airlines hadn't started with the checked baggage fees, getting on early wouldn't be so critical to one's emotional well being.

But just because you drew the short straw on this one doesn't give you the right to pretend to be dyslexic.
